and contemplates improved meansfo'r hold-'1 ing the free-end of the threadagainst uninltentionalunwinding. I a V I In accordance with my lnvention l mount vide another member between which and said resilient member the thread may be inserted,

- and pursuant to. this underlying Conception 1o ,I'contemplate certain further features contributingeflectively to the desired end,

My invention is illustrated in the accom- Panyingdrawings in which Figure 1 is an endgview ofa spool embodying my invention; r a g Figure 2 is anaxial sectional vlew thereof, taken on the plane of .theline 2-2 of Fig;

' ure'l and looking in the direction indicated 20 i and by the arrows;

Figure 3 is an elevational, view lthereof;

Figure 4 is a perspective view of a special" form oftack which is a feature ofmyinvem The spool itself is of woodor other "material and,except for features presently to be'pointedoud isof conventional form com-.

I a prising a cylindrical barrel 5, having an-axial i bore 6," and the flangeTat-each end,; The thread wound fupon} the spool is ind cated *The end jofthe spool is mortised, prefer! ably open at. its 'periphery,.as indicatedat 9,.

this mortise being shallow, of the depthof the straightportion ofthe flange 7,'an'd circular in form. This particular form, however 'is not controllin the mortise ma be of any form and it may be closed as dis'tin Qg uished fromopening at the peripheryof'the" L PQ v An insert, in the form ofa discilopis lodged in'the mortisei9and, preferably,.iit fits l and fillsthe mortise exactly-so as to The "insert 10 is of readily" compressible? orresilient material, suoh a'srubb'er or-jcork,"

to expand, or may be held therein by simple i friction, or by cement or othermeans. ;,As a specific feature of my invention Ipro- 'vide such other means; in-t-hefformof a tack whichmaygalone, orfadditionally,rhold the insert l0, in'place and whichservesthe purpose of providing the other member-between I I which and the resilient insert the loose end sert; The free end ofthe thread, shown at 25, may therefore be inserted under the headof the insert permitting this, r

The arrangement thus described is such that the thread holding means'lies substantially within the conventional contour of the tack may be pressed down to a position enj the tack 11,,as illustrated, the resiliencyof spool. If desired, of course, the head of the v tirely Within the mortise 9,and the insert 10 maybe slightly reduced in thickness, if. a

As illustrated in-Figure 4," the shank of 1 desired, in order to make this possible.

the tack 11 is provided under thehead with a 'cutting edge 12 against which the thread maybe drawn to cut it. Thelower edge 18 i' of the head of the tack is also sharp so that it, too, maybe used as a cutting edge against which the threadmay be drawn to cut it if desired, i p I: claim: I

1. A spool lfor threadicomprising a body, I 1 i a resilient pad, anda tack holding said pad to said body, whereby the free endof the thread may be inserted between the head of said tack and said pad, the shank-of said tack e having a cutting edge thereon.

2. A spool for thread comprisingiabody,

a resilient pad, and a tack holding. said pad to said hodygwhereby the free end of the a thread inayibeinser'ted between the head of said tack and said pad, the edge of said head being a cutting edge. T

1 3. 'A'spool for thread mortised at one end adjacent the periphery thereof, a resilient Q member disposedin saidmortisa'and another r member at the upper face of the resilientv member and between which and said resilient member the free end of thread wound on said spool may be inserted.

4. s 001 for thread comprising a, body a of wood aving a mortise in the end thereof, an insert of resilient material disposed in said mortise, and a tack passing through said insert into said body with its head said insert, whereby the free end of said v 10 thread may be inserted between said head and said body and held in place by the resiliency of said insert.

5. A spool for thread comprising a cylindrical body with a flange, an insert of resilient material lodged in the end of said body and exposed at the periphery of the respective flange, and a tack passim through said insert into said body with its I end engaging said insert, 7, whereby the free end of said 29 thread may be inserted between mid head and said body and held in place by the resiliency of said insert. a

In witness whereof, I hereunto subscribe my name this 16th day of May, 1929.
